Webinar broadcast inspires a very brilliant idea (9)
I believe the answer is:
brainwave
'brilliant idea' is the definition.
'brainwave' can be an answer for 'idea' (I've seen this before). I am unsure of the 'brilliant' bit.
'webinar broadcast inspires a very' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'inspires' means one lot of letters goes inside another (inspire means to breathe in).
'very' becomes 'v' (common abbreviation).
'webinar' anagrammed gives 'brainwe'.
'a'+'v'='av'
'brainwe' placed around 'av' is 'BRAINWAVE'.
Can you help me to learn more?
(Other definitions for brainwave that I've seen before include "Great idea" , "Sudden bright idea" , "Good idea" .)
